Weird Issue: CPU Clock Multiplier Changes During OSD TS only on Single Model at Single Site

Question

Hey Guys - 
I've got a weird issue I need suggestions on, please.  I recently started at a company which already had pretty extensive OSD TS used for all models.  One issue they were having was that a specific model (Dell E5440) at only one specific site would
not only go through the OSD TS slowly, but run slowly after being imaged.  Weird issue!
The Issue
When looking into it today, I ran an extensive report on a machine with the issue and my system which is also an E5440.  I exported the reports (16mb each) to a text file then compared in WinMerge.  When I reached CPU Type, I found the following
difference:
My Machine: Intel Core i7-4600U, 3000 MHz (30 x 100)
E5440 /w Issue: Intel Core i7-4600U, 800 MHz (8 x 100)
As you can see, the multiplier is somehow at 8 instead of 30.  how does this happen during OSD - especially - only at a single site which runs the exact same task sequence? 
I looked through the TS (which I'm still becoming famailer with) but haven't seen anything which would edit the BIOS.  To be honest, I wouldn't even think that changing the CPU clock would be possible with this type of model.
Any ideas or suggestions as to how to fix and/or (more importantly) why this is happening?
Thanks!

Finally found issue.  Wanted to post in case anyone had issue in the future.  Turns out that the issue was not with SCCM.  
The tech at that one site uses the same 65W power adapter for all models at his bench.  As it turns out, the issue was that Intel Speedstep saw the 65W, thought it wasn't enough, so moved
the multiplier down to x8.  
When having them try a 90W power adapter (which shipped with the system,) the issue was resolved and moved back up to where it should be.
Strange as Dell does sell a 65W as an accessory to the E5440, but doesn't mention any speed difference.
Thanks for your suggestions!
